Abstract

This article presents a system for monitoring and diagnosing the performance of operating equipment, in particular power transformers. Since power transformers are the main element of an electrical installation, the reliability of the power supply system depends on their technical state (TS). In our country one of the promising systems for monitoring and diagnostics is Transformer Diagnostics Monitor. The authors have considered the algorithm of this monitoring system and the possibility of its application in digital substations (DSs). Implementation of Transformer Diagnostics Monitor in the automatic control system of a substation prevents electrical equipment from failing, reducing the economic damage from power shortage.
